Abstract:

In recent years, in our living environment, there are various kinds of dangerous gases. However, the weakness of human senses does not allow to determine the type or to quantify the concentration of gas. In order to cope with it, we develop the gas leakage detection sensor, with the high sensitivity and selectivity, especially in the low concentration of the gas. Since the commonly used semiconductor thin films have relatively low sensitivity, long response and recovery times, the studies on material innovations and the novel design have been intensively made. In particular, one-dimensional nanostructures such as nanowires have a very high surface-to-volume ratio. In this lecture, some research contents and trends with respect to the nanowire gas sensor will be introduced.
